Operating notes for UDP broadcast forwarding

Maximum number of entries

The number of UDP broadcast entries and IP helper addresses combined can be up to 16 per
VLAN, with an overall maximum of 2048 on the switch. (IP helper addresses are used with the
switch's DHCP relay operation.)
For example, if VLAN 1 has 2 IP helper addresses configured, you can add up to 14 UDP
forwarding entries in the same VLAN.

TCP/UDP port number ranges

There are three ranges:
Well-known ports: 0 to 1023
Registered ports: 1024 to 49151
Dynamic and/or private ports: 49152 to 65535

Numbers Authority (IANA) website at: www.iana.org.
